{"type":"firestarter.listing","listing":{"id":"lst_3Mv5GsqV","product_name":"Premium Gostwyck Merino Wool Sleeping Bag Liner","category":"Accessories : Resale Accessories","description":"Made from 100% natural, renewable Gostwyck Ultrafine Merino, this isn’t just a sleeping bag liner; it’s a statement piece in your sleep system. The sub-15.5 micron fiber is among the finest merino available anywhere, softer than 99.9% of other merinos, wrapping you in a truly frictionless, itch-free cocoon of comfort night after night on trail.\nThis luxurious Gostwyck merino doesn’t just feel indulgent; it performs at a level that belongs in a no-compromise kit. It moves moisture efficiently and dries dramatically faster than other merinos in humid, heavy air on trails like the Appalachian Trail or Te Araroa, so your sleep never feels damp, clammy, or second-rate.\nThe ultrafine fibers also deliver superior odor control, helping keep your  sleeping bag noticeably fresher for far longer. Whether you’re in a tent, hut, refuge, hostel, or hotel, it adds an extra layer of protection and the quiet satisfaction of knowing you’re sleeping in the finest sleeping bag liner that money can buy.\nCheck out the rest of our Merino Collection.","images":["https://cdn.shopify.com/s/files/1/0004/4652/9572/files/Zpacks-12_2025-MerinoWoolLiner-1.webp?v=1765490100","https://cdn.shopify.com/s/files/1/0004/4652/9572/files/Zpacks-12_2025-MerinoWoolLiner-13.webp?v=1765490100","https://cdn.shopify.com/s/files/1/0004/4652/9572/files/Zpacks-12_2025-MerinoWoolLiner-4.webp?v=1765490100","https://cdn.shopify.com/s/files/1/0004/4652/9572/files/Zpacks-12_2025-MerinoWoolLiner-11.webp?v=1765490100","https://cdn.shopify.com/s/files/1/0004/4652/9572/files/Zpacks-12_2025-MerinoWoolLiner-9.webp?v=1765490100","https://cdn.shopify.com/s/files/1/0004/4652/9572/files/Zpacks-12_2025-MerinoWoolLiner-5.webp?v=1765490100","https://cdn.shopify.com/s/files/1/0004/4652/9572/files/Zpacks-12_2025-MerinoWoolLiner-2.webp?v=1765490100","https://cdn.shopify.com/s/files/1/0004/4652/9572/files/Zpacks-12_2025-MerinoWoolLiner-3.webp?v=1765490100"],"price":199,"currency":"USD","in_stock":true,"inventory_qty":29997,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:39.673Z"},"share_url":"https://firestarter.network/l/lst_3Mv5GsqV","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
